TRS-80 LOADING 

Unless otherwise indicated on the labels, Level I will be on one side of the 
cassette and Level 1 1 on the other. Make sure that your system is on, tha recorder is 
plugged in, and the tape is rewound. Punch out the tabs on the cassette to prevent 
accidental erasure. Now insert the tape into your recorder and press PLAY, 

Type NEW and press ENTER |EK Check the available memory by typing P.M. [El 
for Level I or ?NIEWH'EJ for Level II. Now press PLAY on the recorder and type 
CLOADIEL In about ten seconds two asterisks should appear on your screen, with 
tha right- hand one blinking. If it doesn't bl-nfe, you're not loading. 

The TRS-80 is very sensitive to audio Jewels. If your program doesn't load, rewind 
the tape, adjust the volume level, and repeat the loading sequence above. 

After each toad, run a memory check and note how much memory the program 
uses. 

Should you be unable to load, check the cassette with another system. If It's still 
no go, return it toi

We'll check to see whether it was the cassette or your system that was awry and 
yet you a replacement. 



DISCLAIMER 

Nothing in this world is completely perfect, including this program, t say this 
despite the yeoman efforts of the programmer who originally wrote and debugged 
it and the people in the Instant Software lab who worked far into the New Hamp- 
shire nights, all toward providing you with the best possible program. 

Please enjoy it. If you come up with any improvements, you should let me know 
so I can pass along your ideas to other users. 

Please note that there is no warranty expressed or implied that this program is 
going to do anything other than load and work. We don't guarantee that you will en- 
joy the game programs, that you will make or save money with business programs, 
or learn anything from educational programs. We don't guarantee that you will lose 
weight with a dieting program or avoid disasters with a hioihythm program. But if 
any program causes suffering (other than acute aggravation} or misfortune, we 
want to hear. about it by rnaiJ, not through your lawyer. You are entirely on your 
own in using the programs. 

If you run into problems while using a program, you can communicate with us . . . 
preferably by mail r and we'll try to help out. If a problem turns our io be common^ 
place, we'll put the update information in MICROCOMPUTING. You are supposed 
to read MICROCOMPUTING anyway.

ENTER. The program mill then describe the following rules and 
facilities. 



This is a stock market simulation, in which each person manipu- 
lates an initial investment of $5000 over a twelve-month period. 
This program accommodates as many as six investors. 

A selection of nine different stocks plus one municipal bond is 
offered, from which you can choose your investments. 



Instructions 

After the program is loaded, the computer will ask, 

"HOW MANY INVESTORS?" 

Type in the number of investors (1 to 6). 
The computer will then ask, 

"WHAT ARE THE NAMES OF THE PLAYERS?' 



How to Use Your Investment Facilities

or "BEAR"}, plus realistic, pertinent market commentary. 

Options. You can buy or sell blocks of stock (ten shares to a 
block). 

(a) There is a three-page prospectus for you to review, which 
describes each stock and its dividend potential. 

(b) You can form a trend analysis (graph of stock prices), 
from the beginning of the year to present by viewing each 
monthly graph. 

The "Big Board" (stock-board) displays changing prices, which

CONDITIONS 



Note: The graph illustrates that in February, TWA stock went up 
$5, to a new price of $45 per share. 



Rules 

Price changes occur once each month, allowing you twelve 
opportunities to manipulate your investments. 

If a stock rises in price to exceed $100 per share, a stock split 
is declared. You get two shares for each of the shares you originally 
owned. The price is then divided by two. However, each share 
retains its dividend potential. Consequently, when a stock split 
takes place, you will gain twice the number of dividends. 

If a stock drops below $1 per share, it is declared bankrupt, 
and you lose all your holdings in that stock. 

You can only buy and sell blocks of stock. Each block; consists 
of ten shares. 

Dividends are computed for each investor automatically and are 
then added to his/her cash. 

Each investor's stock prices are evaluated using the newest 
prices, and are added to each investor's cash to reveal the total 
worth of that individual. 

If you wish to buy or sell a block of stock, the following exam- 
ples will illustrate the form of buy or sell order to be typed: 



EXAMPLE:

ATT = Auto-Truck Transport 

FBN « Fly-By-Night Enterprises 

GM ■ Genuine Mobility 

IBM = Investment Buying Management 

PUB = Public Utility Board 

RCA = Realty Conversion Associates 

TRS = Tandy-Radio Shack 

TWA = Third World Associates 

HMB ■ Hometown Municipal Bonds 



"BUY 5 BLOCKS OF TWA' 
"SELL 7 BLOCKS OF IBM' 



or "BUY 5 TWA' 
or "SELL 7 IBM' 



Note: A special feature of this program is the computer over- 
ride. If you attempt to buy more stock than you can afford (or 
sell more stock than you own), the computer calculates the amount 
which is feasible, then completes the transaction. 

If you wish to examine the prospectus, simply type in 

■ "RFVIFW" 

If you wish to examine a graph, type in the words: 

"GRAPH TWA" 
(for TWA in particular) or 
"SHOW ALL GRAPHS" 
(for multi-graph display! 



Graphs display month-by-month growth, stock splits and 
bankruptcies.

Note: After the REVIEW or GRAPH is displayed, the ticker- 
tape is re-run, to remind the investor of the latest trends. 

When an investor finishes his turn, he indicates this fact by 
typing "END". 

There will be instances when the computer has insufficient 
information. 



EXAMPLE: 



"BUY 5" 
(which should be "BUY 5 TWA") 



The computer will reject this statement, and will request a new, 
complete statement. 

After all twBlve months have passed, a last CASH (old CASH 
plus dividends earned) is computed and displayed. Also, a bar-graph 
is displayed, showing the total worth of each investor, by name, on 
a month-by-month basis. 

After the last month of the twelve month period, press the 
ENTER key for the final totals which are displayed in descending 
order (highest to lowest). Then the winner is declared. 

To start a fresh investment year, press the BREAK key and 
type "RUN". Then press the ENTER key.

SPECULATION 



Speculation allows you to find out if you would be able to make 
money on the stock market. 

This is not a game in the conventional sense of the word, since it 
Is a very realistic simulation. The investor starts with any amount 
up to $10,000 in his/her stock purchasing account; a matching 
amount is automatically set up as a savings account at 6.5% interest 
rate. (This interest rate can be altered.) 

The investor refers to newspaper stock prices, to buy and sell 
shares, and all records can be stored on data tape. 

The game can be played for a period of up to five consecutive 
years (simulated by computer), during which time the savings 
account will continue to add and compound quarterly interest. 
The game will automatically give net costs, using real commission 
rates obtained from Merrill- Lynch in October 1978. 

Short of actually investing real cash, this is the closest you can 
come to actually playing the stock market. 



Rules 

(1) You start with $10,000 or less, in your stock purchasing 
account. An equal amount is automatically deposited in your 
sayings account at 6.5% interest rate. 

(2) Vou can alter the beginning amount and the savings account 
interest percentage rate. However, the alterations can only be 
inserted during the first day of a period of speculation. If you 
wish to insert further changes, you must wait until the next 
game to insert them, 

(3) One game of speculation can be extended to cover a period 
from a few months all the way to five years. 

14) Commissions are automatically computed, then added into 
cost and profit predictions when you are analyzing a new 
stock. 

(5) After each 91 days of speculation, the interest is added to your 
savings account, compounding that interest on a quarterly 
basis. 

(6) You may add dividends, paid by various companies, at the 
beginning of each quarter on the following dates: 

January 1st [Caution: Be sure to add dividends quarterly 

April 1st [but only once per quarter] , as this dividend 

July 1st money adds to your spendable money.) 
October 1st 

Note: You simply enter the full amount of these dividends. The 
program will automatically divide the dividend by four (4), then 
deposit the correct amount to your bank account. (It simultan- 
eously deducts the correct amount from the total invested in each 
individual stock.) 

(7) For a stock to qualify for a dividend, you must have owned 
it before the change of the current quarter, 

(8) You will only be able to own up to 25 different stocks at one 
time. 

(9) There are no provisions for selling short in this program, be- 
cause most novice investors are not in the financial position to 
cover possible losses. 

(10) During the process of evaluating a stock you will be asked to 
supply information relating to that stock. Newspapers list 
information on both the New York and American Stock Ex- 
changes, including the following items: 

(a) The name of the stock 

(b) The high and low for the year. 

(c) Dividends paid 

(d) P/E Ratio (Price-to-Earnings Ratio) 

(e) The high and low rates for the week 



(1) The closing price for the week 

(g) The net change of rate for the week 

(11) If you can't get information about the earnings of a particu- 
lar company, use the P/E ratio, (Sometimes the projected 
earnings are putalished.l These facts are listed in the news- 
papers when the company announces its earnings for a year or 
a quarter. 

Note: The actual earnings of a company provide more 
accurate predictions. 

(12) To calculate EARNING RATIOS: 

The stock price is divided by earnings (STOCK PRICE/ 
EARNINGS). 

The lower the P/E ratio, the more net earnings the stock 
yields per share. This Is considered a good way to evaluate 
stock, although conversely, many times a stock does quite 
well with ratios of 20-to-1 and even 30-to-1 . 

(13) Formulae for future price projections in this program depend 
entirely upon raw data (disregarding up-coming contracts or 
recalls of merchandise, which are not indicated by company 
earnings). 

(14) After loading the program, you will answer the following 
questions: 

"IS THIS YOUR FIRST DAY IN THE MARKET (YES/NOI7" 
"WHAT IS THE MONTH, DAY, YEAR NUMERICALLY 

XX,XX,XX" 
"NUMERICALLY THIS IS NOW DAY NUMBER XXX OF 

THE YEAR" 
"WHAT ORIGINAL AMOUNT DO YOU WANT IN EACH 

ACCOUNT XXXXXX" 
"DO YOU WISH TO CHANGE FROM 6.5% INTEREST 

(YES/NO)?" 
"ENTER INTEREST TO BE EARNED ON ACCOUNT" 

(15) Press the ENTER key, to obtain the following display:

Notes 

(161 Try not to panic-sell when the market fluctuates. The market 
has done this for many years. Hang in there, and make money! 
(1 7) Don't put all your money into one stock. 

(18) Keep as much of your money invested as possible; it cannot 
grow if it is not invested. 

(19) The laws of chance dictate that any stock can go stale after 
purchase - you might face some deep frustration! 

(20) This program is not intended to aid you in the actual purchase 
and choosing of real stocks. No guarantee of predictions 
should be presumed, and none is made.

ACCIDENTAL ERASING 

Until vou've triad it, you won't believe how easy ■! <s to screw up a data cassette. 
For instance, th& magnet in any Jovdspeeker cart do 3 fantastic job of removing 
part of the data , . . and you'll find loudspeakers in portable radios, cassette record- 
eri, TV sets. etc. Power supplies will do even better, No one can even estimate how 
many tapes have been wiped out by these little THS-80 power units . . . or by putting 
cassettes on top of the monitors, where its electromagnetic field can weave its subtle 
work. 

Oo not treat your cassettes casually. Give them extra care and attention, Keep 
them away from anything) electrical, magnetic or dusty at all limes. 

Well, accidents can happen, even to the most careful of us, One of your kich can 
try out a data cassette and push the record button . . . etc . You should ward this off 
by punching out the tabs on rhe back of the cassette to prevent recording. If things 
do go awry, we'll redo your cassette for you for a nominal service charge of $2. Just 
send back the originaT cassette, a note as to what went wrong (we like to keep 
statistics! find the $2. We'll fix it up for you and get it back as quickly as we can Try

CASSETTE RECORDER 
MAINTENANCE 

Often when you have trouble loading a program, it's not rhe fauH of (he tape or 
your computer system, ft may be a problem with your cassette recorder. The staff 
at Instant Software use a large vartety of cassette recorders eight hours a day, five 
days a week. To insure that the recorders will keep up wilh the demands of our work 

load, they are subjected to a rigorous maintenance routine. 

As ynu run a tape in any recorder, a particle of oxide may flake off the tape, or a 
bit of dust may settle from the air, These bits of debris may arthers to the 
play/record head, causing variations in the volume level and degrading the perfor- 
im;imi:i' Ol ynur u-.:oi.li:r 

To keep youT recorder in top condition, clean the recorder heads regularly after 
every 15-20 loads or saves. Use denatured alcohol (available at any drugstore) and 
cotton tipped swabs. Lightly dampen a swab and gently stroke the erase head, the 
record/ptay head, and the pinch roller. This will remove accumulated tape oxide 
and dust, You can also use a soft brush or vacuum cleaner to remove dust from ihe 
tape com panment, 

Every lime you press the rccotd tjr play burton, you put a smafl amount of stress 
on the play /record head. Eventually the head will be pushed oui of alignment, Thss 
is one of the reasons why a program recorded when you first got your sytem will 
not toad several months latei or won't load on another system. 

The cure is to have your recorder aligned by a qualified technician, or if you have 
the know-how. to align it yourself. 

The technicians at histant Software recommend using an industrial standard 
alignment tape (they use a Panasonic tape, part No. OZZCFM}. This tape allows 
them to test for playback frequency response, playback level, and ihe head azimuth 
adjustment. The most critical aspect, especially for PETs, is the azimuth adjustment.. 

To run a lest on your recorder, connect an oscilloscope to the earphone jack, in- 
sert the alignment tape into the recorder, push the play button, and adjust the head 
tor the best waveform on the oscillosocope. If you lack tesi ins i rum en ts. adjust the 
head for the loudest sound and the best high frequency response without changing 
the recorder's volume setting. 

Remember, your recorder is a critical link in your computer system. For the best 
performance, give it the best care 



IMPROVEMENTS 

There arc very few programs which cannot be improved. If you work out some 
improvements 10 this program, it could be worth your white to send them in for 
possible use in an updated version of the program. Those who contribute to an up- 
dated program will share in the royalties which result. Instant Software Inc. Peter-
